The EVERUN midsole offers excellent energy return, making it suitable for both daily training and longer runs. The ISOFIT upper ensures a comfortable, sock-like fit, while the TRI-FLEX outsole provides great traction on various surfaces. However, the insole construction could be improved, as some users reported issues with it riding up during runs. Additionally, the price point is on the higher side, which may deter some potential buyers. Overall, the Saucony Liberty ISO 2 is a solid choice for runners seeking a fast, supportive shoe for distances up to a half marathon. Its combination of stability and responsiveness makes it a standout option in the stability running shoe category.
The Saucony Liberty ISO 2 features several updates from the previous model, the Saucony Liberty ISO. The upper has been redesigned with a new knit material and ISOFIBER reinforcements for a more secure fit. The heel counter has also been updated to provide better lockdown without the use of a plastic exoskeleton. Additionally, the medial post has been extended to offer enhanced support for overpronators. These updates make the Liberty ISO 2 a more comfortable and supportive option compared to its predecessor.

The Vongo also tends to be slightly more cushioned, making it a better option for those who prioritize comfort over speed.
